Every so often, a file lands on your Mac that it simply cannot open. A .msg from a colleague on Windows. A winmail.dat attachment that arrived instead of the email that you were expecting. An archived email someone dug out of an old Outlook export.
MailRaider is the app that opens them, and it has been since 2009 - longer than any other tool on the Mac App Store. It handles these formats the way they were meant to be read: preserving full formatting, embedded images, and attachments as far as possible.
What MailRaider opens:
.msg – Microsoft Outlook messages
.eml – standard email format
.oft – Outlook template files
winmail.dat – the mystery attachment that hides what was actually sent
What you can do with them:
Read emails with full formatting, colour-coded headers, and embedded images
View and extract attachments
Export to PDF, RTF, or EML to keep a portable copy (save them to MailRaider on your iPhone or iPad!)
Export contacts to .vcf and calendar appointments to .ics
Drag (or double click) files straight from Finder — it just works
If you need to process large archives, work with PST or OLK mailboxes, MailRaider Pro has you covered. But if your needs are more straightforward – you get these files occasionally and you just need to open them – this is exactly what you need.
No subscription. Pay once.

A lifesaver if you have clients who forward you Windows .msg files

I forgot I’d had this app when a client sent me a bunch of .msg files from Windows Outlook with both text and photos I needed for a job. Mailraider opened the messages without a hitch and let me save the text of the emails AND the photos that were attached to it. Easy. Trouble-free. I saved in an RTF Archive to automatically extract the text and attachments into one folder. You can save as 3 other formats as well, but this one was what i needed. This app is a lifesaver if you have clients who forward you Windows email .msg files.
It opens .msg files and can save them to .eml files - sometimes

I wanted an app that would open .msg files and export them to .eml files. This app does exactly that - occasionally. I didn't want something that converts .pst files. Instead I wanted something to open individual e-mail messages created in Outlook 2003 on the PC and convert them to a format I could use in Outlook 2011 for the Mac. This seems to do the job but only intermittently. I can't determine a reason why it will succeed in converting some .msg files and not others.It always seems to be able to convert messages to .rtf files.It truncates the names of attached files.I tried to save only Excel files that were attached to .msg files. It seems to recognize the existence of only .xls files, not .xlsx files. So while it will successfully save an attached Excel file to my desktop I will sometimes have to relabel the suffix from .xls to .xlsx. Then Excel opens the file and repairs it, after which the file appears to be intact.I haven't tried handling any other attachment file types.This app always opens the .msg file and allows me to view it. It always allows me to save the message as a .rtf, but it is very unreliable at saving files in .eml format.I can use this app as a stopgap measure until it is updated to reliably convert .msg to .eml.
Update for Big Sur?

Love this app, it has saved me multiple times. However, since Big Sur, the attachment download function hasn't worked. Any plans to up date the app for Big Sur?
Plain text only.

Doesn’t open the msg file in anything but plain text, nor does it open any attachments. Wish I would have known this *BEFORE* I purchased the software.
Developer Response
The information that this version only opens plain text is clearly stated in the information provided on the purchase screen for MailRaider on the App Store. To open email, preserving formatting, you need MailRaider Pro.As to opening attachments - it does.
